Hi boys and girls. I noticed that Emirates has often much cheaper fares in first class than other airlines.

E.g. from ZRH to SIN (prices in EUR according to ITA)
- Air France 9543
- BA 9092
- Emirates 3398
- Lufthansa 8431
- Swiss 5765

Now my first question: Why is Emirates often so much cheaper than their competitors? Is there something "wrong" with EKs first class? I heard so far only good things but the "cheap" price makes me thinking if there is something worse than first class with other airlines. I flow so far only Swiss first class in an A340.
